No one?

Ph seems to be the problem. 6.9 is SUPER acidic for hydro. It should be at a decently stable 5.5 ph.

make sure your nutes are low and you add more as it gets bigger. I dont grow hydro but at this size I would imagine you wouldn't need more than about 200 ppm at this point.

Any hydro growers want to chime in?

[redtails]

I don't grow hydro either, but it looks like a pH problem I had in soil a little while ago. The leaves would get those spot and become crispy...It was nutrient lockout from high pH, not sure which ones are effected but it should stop when you get the pH more stable I'd imagine.

Yea, I am having issues keeping PH stable. I am adjusting now to 5.0 and 8 hours later its 6.3. Any ideas how to stabilize it?

[Stickyrickey]

Bump for advise on stabilizing PH....
